Shido is an eccentric player in Blue Lock who has a strong penchant for violence or, more specifically, physical altercations. At the core of Shido's personality is a drive to play football because it is a biological phenomenon that makes him feel complete. Shido scores goals to pass on his genes and leave his mark on the world; it is his sole focus. He gets excited from playing high level football with other high-level players and is bored if people cannot make him "explode" or don't "explode".
